<p>The following list documents the sources of data in the ./data/ChemData.csv
file.</p>
<ul class="simple">
<li><p>Molecular weights (M) are from the periodic table in Fine &amp; Beall, 1990,
Chemistry for Engineers and Scientists, Saunders College Publishing:
Philedelphia, Pennsylvania. Data are in (g/mol).</p></li>
<li><p>Critical-point data (Pc, Tc, Vc) are mostly from McCain, 1990, The
Properties of Petroleum Fluids, 2nd Edition, PennWell Books: Tulsa,
Oklahoma. Exceptions are for Argon, which is from P.4-127 of the Handbook of
Chemistry and Physics, 71st Edition. The data are in psia for pressure and R
for temperature.</p></li>
<li><p>Boiling point (Tb, Vb) are from Poling et al., 2001, The Properties of gases
and liquids, 5th ed., McGraw Hill. Data not in Poling et al. are from the
group contribution method by Kurtz and Sankin, 1954, Calculation of molar
volumes of hydrocarbons over a wide range of temperatures and pressures,
Industrial and Engineering Chemistry, 46(10), 2186-2191.</p></li>
<li><p>Acentric factors (omega) are mostly from McCain, 1990, The Properties of
Petroleum Fluids, 2nd Edition, PennWell Books: Tulsa, Oklahoma. Exceptions
are for Argon, which is from P.4-127 of the Handbook of Chemistry and
Physics, 71st Edition. The data are in psia for pressure and R for
temperature.</p></li>
<li><p>Henry’s law constants (kh_0) are from Sander 1999, Compilation of Henry’s
Law Constants for Inorganic and Organic Species of Potential Importance in
Environmental Chemistry, downloaded from
<a class="reference external" href="http://www.rolf-sander.net/henry/henry.pdf">http://www.rolf-sander.net/henry/henry.pdf</a> on January 2, 2012. The data are
in mol/(dm^3 atm).</p></li>
<li><p>Enthalpy of solution (dH_solR) are from Sander 1999, Compilation of Henry’s
Law Constants for Inorganic and Organic Species of Potential Importance in
Environmental Chemistry, downloaded from
<a class="reference external" href="http://www.rolf-sander.net/henry/henry.pdf">http://www.rolf-sander.net/henry/henry.pdf</a> on January 2, 2012. The data in
the table are the negative of the enthalpy of solution (so that the values
are positive) and are normalized by the universal gas constant R and
reported in K.</p></li>
<li><p>Specific volume at infinite dilution (nu_bar) are from Wilhelm et al., 1977,
Low-pressure solubility of gases in liquid water, Chemical Reviews, 77(2):
pp. 219-262.</p></li>
<li><p>Diffusivity model coefficients (B, dE) are from Wise and Houghton, 1966,
The diffusion coefficients of ten slightly soluble gases in water at
10-60 deg C, Chemical Engineering Science, 21: pp. 999-1010.  The data are
in cm^2/sec (B) and cal/mol (dE).</p></li>
